Step-by-step explanation:
Answer:
34 pages
Step-by-step explanation:
For the first three pages, Sonia is already down 13 dollars.
106-13=93 dollars left
93/3 dollars per page =31
31+those three first pages=34 pages
4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5 per minute.
Step-by-step explanation:
The given is,
Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
Oil drained at a rate of 2.5 per minute.
Step:1
Time taken to dry the oil tank is,
T = ....................................(1)
Step:2
Volume of the oil is,
.................................................(2)
Where, r - Radius of Cylinder
r = 1.1 ft
From eqn (1),
V = × × 3
= 11.40398
Step:3
From equation (1)
=
= 4.56
= 4.56 minutes
T = 4 minutes 34 seconds
Result:
Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
Answer:
Explained below.
Step-by-step explanation:
There are quite a few examples of this but I will go with what is common in physics which is "acceleration due to gravity".
Acceleration due to gravity is positive when an object is falling down in the direction of gravity but negative when it is thrown upwards and acting against gravity motion.
Thus;
g_downwards = 9.8 m/s²
g_upwards = -9.8 m/s²
If acceleration due to gravity is zero, it means that the object is at the centre of the earth because at that point g = 0.
Answer:
-34.3
Step-by-step explanation:
distribute 5 through the ()
3(x+35-5x+27)+11 = 94-15x
combine like terms
3(-4x + 62) + 11 = 94-15x
distribute 3 through ()
-12x+186+11 = 94-15x
combine like terms
-12x+197 = 94-15x
add 15x to both sides. subtract 197 from both sides.
3x=-103
divide both sides by 3
x= -103/3 which is also equal to -34.3
